Products

BioHaven floating Island products mimic natural wetlands in form and function. 

floating island products work by acting as a matrix to clean HABs

All BioHaven products share the same unique characteristic: the high volume of bio-reactive surface area provided by the high-tech matrix. Upon launching, the matrix delivers instant benefits and continues to deliver habitat and water quality improvements throughout its long life. Its longevity is assured by the protective armor coating it receives during the manufacturing process.

Floating island products are a green infrastructure solution.

The BioHaven matrix is robust, tolerant of wind and waves in high-energy settings. It is inert and long-lasting as well as lightweight and flexible. BioHaven technology is a sustainable, green, infrastructure solution that provides benefit to any waterbody.

BioHaven products are completely customizable.

BioHaven solutions can be configured passively, actively, or in combination. For large projects, such as water resource recovery and wastewater projects, BioHaven products can be scaled up to whatever size our proprietary modeling program determines is required. Projects all benefit from natural circulation through the biofilm-covered surface area of BioHaven Floating Islands. Projects requiring active airlift technology to aerate or to force water to circulate more aggressively through the matrix can utilize one of our StreamBed systems or add nanobubbler technology.

BioHaven technology is proven and trusted.

The BioHaven platform has been chosen by NASA plant scientists to deliver their patented technologies for water remediation and nutrient recovery projects. Customers also include US Department of Agriculture, the City of Los Angeles, and over 9,000 applications worldwide.

    BioHaven Floating Islands

    Our original product, BioHaven Floating Islands (BFIs) come in two standard sizes, large and small. They are a superb platform for allowing the bushy-rooting perennial plants that grow through the matrix to fully mature and form an extensive root biomass below the island. The upper layers of matrix lie above water level, ensuring the oxygen transfer necessary for plants to thrive; once their roots descend into water, they pull their nutrients from below, resulting in clean water and healthy fish. A huge range of wetland and non-wetland plant species thrive in our matrix, including specialized hyperaccumulator plants. They are completely customizable in all aspects for the needs of your waterbody and your desired purpose.  BFIs can be joined together in a cluster for larger projects requiring greater nutrient removal, fish aggregation, or aesthetics.

    Much more information about the larger scale benefits and uses of our floating islands can be found on our Home Page.

    Floating islands can be fun as well as functional. How about a floating dock, yoga platform, putting green, or private island for your pond? A BioHaven Living Walkway combines the benefits of a conventional docking system with construction that improves water quality, vegetation, and habitat benefits. Mini pond islands are great for koi ponds, turtle ponds, small water gardens, and even container gardening.

    Our smaller floating islands are suitable for low-wind, low-wave environments. Size and buoyancy can be customized.

    • Mini-BioHavens are small islands for ponds and are exclusively available from our licensee Floating Islands West.

    What about a a low profile duck blind that will camouflage into the surrounding environment? The Floating Duck Blind is a platform of matrix decked with non-skid fiberglass lumber. A coated steel fencing box sits on top of the decked platform which houses all of the creature comforts including a bench, gun holders, a shelf, and dog kennels. An outer edge of exposed matrix wraps around the fencing to allow for vegetation to be planted into pre-drilled holes.

    For windy, unprotected, or ocean environments, see our High-Energy BioHaven (HEBs).


    BioHaven Habitat Islands

    BioHaven Habitat Islands are successful for creating just what their name says: habitat! Swans, loons, amphibians, turtles all love our islands. Uses include replacing wild natural habitat lost to rising sea levels, establishing new habitats for migration routes, attracting wild birds to your property for viewing or hunting, creating an aesthetic focal point in a body of water. It does these things while also remediating algae overgrowth and excess nutrients and delivering clear water.

    They can also be used for human habitat! BioHaven islands are a way to literally grow more landmass for human recreation, education, or most conceivable purposes.


    BioHaven Streambed (BSB) / Forced-Flow StreamBed (FFSB)

    BSBs integrate an efficient, low-energy airlift system into the BioHaven matrix. There are two standard models:

    • The BSB has a stream channel on top that allows deep water to be drawn up into it and exposed to the atmosphere. Its main purpose is aeration.
    • The Forced-Flow BSB sits mostly below the waterline to promote optimal biofilm growth. The stream channel is submerged, allowing water to circulate through the matrix under pressure. Its main purpose is forced circulation particularly in a wastewater environment.

    Both BSBs can be anchored or tethered. The blower assembly in both systems is housed onshore.


    WasteWater BioHaven (WWB)

    WWBs are passive BioHaven modules specifically designed to be scaled up for treatment applications. They are joined together with corrosion-proof fittings and tethered to shore. Easy access for maintenance is designed in through a central walkway.


    High-Energy BioHavens (HEB-W, HEB-N)

    HEBs are substantial BioHaven modules engineered for settings that experience high winds or waves. HEBs have multiple anchor points for extra security in tough conditions. Vegetated EcoShield™ uses BioHaven matrix technology to protect stream banks and the leading edge of coastal systems from erosion.

    • High-Energy BioHaven modules are available exclusively from our partner Martin EcoSystems.

    Solar NanoHavens

    Our solar-powered NanoHaven is a unit that can be installed singly or in multiples to treat Harmful Algae Blooms (HABs) and many other water problems. It consists of one or more state-of-the-art nanobubblers mounted on framed BioHaven modules, along with solar panels to provide operating power. It can be implemented in remote, off-grid spots, wastewater lagoons and ponds and lakes of all shapes and sizes with an appropriate water depth. Low-growing hyperaccumulator plants can be added to facilitate the removal of extreme pollutants.

    ​NanoHaven combat units are an accelerated, one-time treatment system, requiring infrequent maintenance.

    BioHaven Floating Photovoltaics (FPV BioHaven)

    A multi-benefit platform for floating photovoltaics, BioHaven floating islands provide a resilient, durable and stable support that holds the panels low to water. Its flexible, permeable materials dissipate wave energy and support the biology that eradicates HABs and other water issues while the solar panels generate clean energy above. BioHaven FPV cools the water and prevents evaporative loss.

    BioHaven FPV is green infrastructure with 12 years of independent research attesting to its performance in municipal and private water treatment. Research attests to the BioHaven matrix safety even in drinking water reservoirs, greatly expanding the geography for FPV installations.

  • About the BioHaven Matrix

    BioHaven Floating Islands are made of inert, long-lasting materials that are fit-for-purpose and certified safe for use in the environment. The BioHaven matrix is manufactured with 100% recycled PET-sourced from plastic drinking bottles. Every BioHaven receives a polyurea coating of ‘armor’ that maintains its integrity against UV damage and against the pecking of ducks and geese. The armor is the same material that is used to line municipal concrete water tanks and truck beds and meets food-grade quality standards.

  • Environmental Safety Statement

    FII avoids the use of organic materials that readily break down and contribute to aquatic oxygen depletion. The BioHaven matrix is manufactured with 100% recycled PET-sourced from plastic drinking bottles. These are mandated by the FDA to use the highest quality fiber available. Its high intrinsic viscosity (IV) ensures the quality of recycled matrix fiber exceeds most virgin fibers. The recycling of this PET fiber keeps millions of bottles out of landfills each year.

    Every BioHaven receives a polyurea coating of ‘armor’ that maintains its integrity against UV damage and against the pecking of ducks and geese. The armor is the same material that is used to line municipal concrete water tanks and truck beds and meets food-grade quality standards. BioHavens are lightweight when dry and can be handled safely without the use of heavy equipment. If they have to be removed from their waterbody for any reason, drying them out on shore first will facilitate transportation.

    It is important to note that PET sinks and is not found in the floating garbage gyres in the ocean. Today, there are legitimate concerns about microplastics in water which are too small for normal filters to remove. Specifically, these are beads used in exfoliants and such. BioHavens are actually one of the few technologies that can remove them because they stick to biofilm-covered surfaces.

    After 15 years of rigorous testing, no side effects have occurred utilizing BioHaven technology. When we consider the multitude of noxious and harmful pollutants known to be in water, BioHaven’s proven ability benefits the overall environment.

  • How Plastic Will Save Our Water
  • Floating Island Planting & Launching Manual

    DIY Floating Island Planting Manual These instructions are for our traditional empty pocket/no plug floating islands, and islands with solar, nanobubble, or biochar applications may have different instructions. Users of these products should reach out to their Island Masters.

    Components

    1. The BioHaven Floating Island ships as a single unit, shrink-wrapped.
    2. Multiple islands in the same order may be palletized.
    3. Each island contains two anchor points.

    Customer to Supply

    • Visqueen for placing island on prior to launch.
    • Anchors – 130lbs. total anchor weight for a BioHaven-L and 60lbs total anchor weight for a BioHaven-S. Avoid cinder blocks where there is a pond liner in place as they can damage the smooth surface.
    • Plastic-coated chain for attaching island to anchors (3/16-inch) – Length: depth of water plus 20% (to allow for high-water event) plus 5 ft. for looping round anchor).
    • 2 secure clips – one clip for each end of the anchor cable.
    • Plants or seeds – 24 per small island, 60 per large island.
    • Potting soil. Coco-peat can be used. Avoid using heavy soil with a clay or sand base. If planting bare-root plugs use potting soil and no peat as peat may burn the roots.

    Delivery
    • Single islands can be lifted by two people. The Biohaven-L weighs 260 lbs, the BioHaven-S weighs 100 lbs.
    • Personnel required to handle and launch island: 1 or 2 people.
    • The customer is required to carry out a delivery inspection and sign-off (or exception) to validate the warranty.

    Site Preparation
    1. Identify a level site from where you can launch the island.
    2. Lay out the Visqueen right next to water’s edge, allowing it to drape slightly into the water.
    3. Assemble anchor(s), cable, soil, plants / seeds and tools.
    4. Sink tether stakes (rebar or bollards) if planning to tether the islands.

    Step 1: Island Preparation
    1. Place the island face-up on the Visqueen, with the planting pockets on top, close to water’s edge.
    2. Lift the island slightly so you can access the anchor eyebolt ring and attach your anchor chain, stretching it out so that it extends beyond the island. Do both sides.
    3. Attach the other end to your anchor (if using cinder blocks, pass the chain through the blocks and secure the end back to the chain to form a loop).
    4. BioHavens can be anchored individually or can be joined together to form a cluster.
    5. If you are joining several islands together, see instructions below.

    Step 2: Installing a cluster of islands
    1. If space permits, place all the islands you are going to launch on a tarp close to the shoreline, in the order they will be once in the water.
    2. Depending on how many islands you have, use the following joining methods: a) Link the outer islands in a circle. b) Link interior islands to the outer islands with chain using the outer island’s eyebolt or its attachment chain.  c) PVC pipes can be used to keep the islands apart and stop them bumping into each other. d) Anchor the cluster at three points (at least). e) You can position and anchor each island individually without joining them together, making sure you allow enough space between them to stop the anchor chains getting tangled up in windy conditions.
    3. If you do not have space to lay out the whole island array on shore, you will need to launch them one-by-one, making sure you attach the next island while still on shore before pushing each one into the water.

    Step 3: Planting
    Note: the key to successful planting is making sure there are no air gaps in the soil. It is important to pack down the soil tightly at each stage.
    1. Fill the planting hole about halfway with peat / soil mixture and tamp it down firmly.
    2. Water the planting pockets using a hose or watering can.
    3. Place the plants root-down in the planting pockets. Make sure the root is pointing downwards.
    4. You can keep the plant in the soil it comes with, or remove to fit.
    5. Add more soil and tamp it down firmly until the soil is just above the top of the planting pocket.
    6. Water the plants thoroughly. If the soil mix sinks more than a half-inch below the planting pocket, add some more.
    7. If using, install waterfowl fencing and netting.

    Step 4: Launch
    1. Place anchor on top of the island.
    2. Carefully push the island or island cluster into the water.
    3. Thoroughly soak the plants (again) and ensure the top of the planting pockets are wet and stay wet.
    4. Maneuver / tow into position then drop the anchor(s) slowly into the water.

    Step 5: Post-launch
    1. Check that planting pockets are wet to the top.
    2. In the first 2 weeks, carry out frequent checks to ensure the plants are growing, the anchor is holding and there are no unexpected issues with the island.
    3. Once a month or so after this, check the island periodically and remove any undesired plants (weeds) that may be growing on the island.

    Options
    Tethering:

    If your island has tether points rather than anchor points, use these instructions in place of the anchoring instructions. Tethers have the ring on top of the island, beside the planting holes; anchors have the rings under the island.

    1. During site preparation, put the tether points in place. These can be on shore, below the water level or tie-offs to a buoy or other stable fixture.
    2. Measure out the length of your tether rope and add 2 feet to allow for tying off at both ends.
    3. Before adding plants, secure the tether to the ring on top of the island with a clip or knot. Keep the other end on shore (tie it loosely to something, eg a brick, to keep it from sliding into the water).
    4. Repeat if using two tethers.

    Planting with sod:

    1. When planting an island with sod, spread a light layer of soil mixture (approximately 1” thick) across the top of the island.
    2. Remove as much of the mud as possible from the sod roots.
    3. Lay sod on the island, cutting to fit, until the entire top is covered. Allow the sod to overlap edges so that the sod covers half of the side of the islands. Sod should be even with the waterline when launched.
    4. Pin the sod into position with landscape pins – about 2 pins per square foot.
    5. If planting plants along with sod, place landscape flags in the sod above the planting holes so that the holes can be located for planting the plants. Remove the landscape flags one at a time as you cut through the sod to expose the hole.
